5 Claims. 1

The invention relates to tools and relates more particularly to a tool for handling packages of yarn. V

In the textile industry, it is common practice to form packages of yarn by winding yarn onto a tubular support. Great difiiculty has been experienced in the handling of the yarn packages during production, inspection, transfer, wrapping, packing and other operations wherein manual contact with the packages of yarn is necessary. Since the packages of yarn may weigh up to four or more pounds and since they are normally not provided with means for handling the same whereby contact with the yarn may be avoided, the danger of soiling and damaging the yarn and of disarranging the windings on the yarn packages is ever present even with the most careful handling of the yarn packages by skilled operatives.

It is an important object of this invention to provide a tool for handling packages of yarn which will overcome the difficulties previously experienced in handling said packages of yarn and which will be especially simple in construction and efficient in use.

A further object of this invention is the provision of a tool for handling packages of yarn which will engage said packages without contacting the yarn so as to avoid damage to the yarn or to the uniformity of the winding on said packages.

Other objects of this invention will be apparent from the following detailed description and claims.

The present invention is particularly concerned with handling cones of yarn, each of which comprises a tubular support of generally conical shape having yarn windings thereon, and having at one end thereof an internal rim forming a circular opening communicating with the interior of the tubular support. For handling these cones of yarn to prevent contact with the yarn windings thereof, we have provided a tool comprising a finger adapted to enter into the tubular support,'which finger is operatively connected to a handle of convenient size and shape. The finger is provided with means, such as a notch, for engaging the rim of the tubular support when the finger is inserted in the interior of the tubular support, and with the area adapted to contact the interior of the tubular support at a point spaced from the rim and diametrically opposed to the point at which the rim is engaged. Advantageously, the handle lies in the plane of the finge and is inclined at an angle in the same general direction as that in which the notch opens so that when the tool is engaged with a package of yarn, the handle will be inclined with respect to the axis of the tubular support. The inclination of the handle serves to improve the ease with which the tool may be handled in that a person using said tool need Ibend his wrist to only a limited extent to insert or remove the finger from engagement with the tubular support when the cone is positioned on a horizontal surface with the tubular support disposed vertically. It also serves to align the tool in the. hands of a user for proper engagement with the cone.

Preferred embodiments of this invention are shown in the accompanying drawing wherein Fig. l is a perspective view of the tool,

Fig. 2 is a side elevational view, partly in crosssection, showing the engagement of the tool with a cone of yarn during the lifting thereof, and

Fig. 3 is a perspective view of a gang tool for simultaneously handling a plurality of cones of yarn.

Referring now to the drawing, the reference numeral H (see Figure 2) designates generally a cone of yarn, comprising a tubular support. I2 of conical shape having thereon yam windings I3. At its upper or narrower end, the tubular support I2 is provided with'an internalrim I 4 forming an opening I5 which communicates with the interior of the tubular support.

For handling the cones ll, there is provided a tool, indicated generally by reference numeral IS. The tool l6 comprises a handle l1, having acircular boss l8 at one end thereof. Projecting from the under surface of the boss l8 isa finger l 9 that is of such size and shape as to pass readily through the opening [5. In one surface of the finger l9, there is a. notch 2| having a surface 22 that is normal to the plane of the undersurface of the boss l8 and a shoulder 23 that is normal to the plane of surface 22. The finger I9 is curved in a direction away from that in which the notchZl opens and terminates in a'surface 24 for engaging the interior of the tubular support l2.

During use, the finger l9 of the tool I6 is inserted through the opening I5 and into the interior of the tubular support I2. Upon raising the cone H, the notch 2| will engage the rim H to prevent the cone H from slipping off the tool It and the surface 24 will abut the inner surface of the tubular support l2 at a point spaced from said rim and diametrically opposed to that at which the notch 2| engages the rim I 4. As shown in the drawing, the surface 24 is inclined so that it will contact the inner surface of the tubular support I2 over an extended area when the cone H is raised, to avoid the application of concentrated forces to said support.

The handle I! lies in the plane of the finger l9 and is inclined at an angle of from about 30 to 60 degrees in the same general direction as that in which the notch 21 opens. Because of the inclination of the handle [1, a person handling the tool I6 need bend his Wrist to only a limited extent to insert or remove the finger l9 from the opening l when the cone H is positioned on a horizontal surface with the tubular support l2 disposed vertically, making for easier use of the tool. In addition, the inclination of the handle 11 tends to align the tool it automatically in the hands of a user with the notch 2| and the surface 24 positioned properly to engage the tubular support l2, at the rim M and the interior surface, respectively.

Fig. 3 shows a gang tool, indicated generally by reference numeral for simultaneously handling six cones H. The tool 25 comprises a rectangular bar 28, to one surface of which is fastened a pair of handles 21 and from the other surface of which project six fingers 23 identical in construction with the finger 19. While the tool 25 has been shown as having six fingers 28 for handling six cones of yarn, it may have a smaller or larger number of fingers 28 for handling any desired number of cones of yarn.

It is to be understood that the foregoing detailed description is given merely by way of illustration and that many variations may be made therein without departing from the spirit of our invention.

Having described our invention, what we desire to secure by Letters Patent is:
